Description
Technical field
The utility model relates to a kind of pressure governor, particularly relates to a kind of diaphragm type pressure governor.
Background technique
Gas pressure regulator, governor is commonly called as reduction valve, is gas flow by automatically changing through modulating valve and makes outlet gas keep the equipment of authorized pressure, being usually divided into direct acting type and indirect acting type two kinds.Pressure governor is how a kind of flow of no matter gas and upstream pressure change, and can keep the device that downstream pressure is stable.Pressure governor should be able to: one, upstream pressure is reduced to a stable downstream pressure; Two, downstream pressure should be able to be limited when pressure governor breaks down in safety range.
Direct acting type pressure governor is made up of measuring cell (film), transmission part (valve rod) and controlling mechanism (valve).When the gas consumption after exporting increases or inlet pressure reduces, outlet pressure just declines, at this moment the pressure reflected by PRESSURE PIPE makes the power acted on the downside of film be less than the power of pouring weight (or spring) on film, film declines, flap is also along with valve rod moves down, make valve open greatly, gas flow increases, and outlet pressure returns to originally given numerical value.Otherwise when the gas consumption after exporting reduces or inlet pressure raises, valve turns down, flow reduces, and still makes outlet pressure be restored.The weight of exit pressure levels available adjustment pouring weight or spring force come given.Small liquid petroleum gas reduction valve and service regulator are all direct acting types.
The regulation precision of direct acting type pressure governor is low; Pressure control range is narrow; Due to by epithelium size restrictions, be difficult to accomplish large gauge valve body; Flow passing capacity is poor.The axial flow pressure regulator working principle of indirect acting type: pressure governor is made up of air inlet valve body, air inlet junctor, junctor of giving vent to anger, valve body of giving vent to anger, pilot valve five major part, and air inlet junctor is built with main valve pressure regulation spring, high pressure air jacket casing, sealed Cellophane etc.Give vent to anger valve body built with fixed valve base, and this valve seat and high pressure air jacket casing form sealing pair.When pilot valve is closed, under gas cylinder is enclosed within the effect of main valve spring, be close on fixed valve base, medium be closed in pressure governor; When pilot valve is opened, under the effect of the first air guide of pilot valve, sealed Cellophane pulls sealing film platen pressuring spring, high pressure air jacket casing is made to leave fixed valve base, command valve is opened larger, gap between high pressure air jacket casing and fixed valve base is larger, thus realizes the function regulating stream pressure height and uninterrupted.Axial flow pressure regulator entirety is heavier, involves great expense, and maintenance, repair are inconvenient.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of diaphragm type pressure governor, and its structure is simple, and maintenance, repair are convenient, reduces cost of production.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of diaphragm type pressure governor, it is characterized in that, it comprises the first bolt, valve body, one O type circle, 2nd O type circle, plug, stud bolt, nut, upper cover, lower cover, tapered sleeve, base, second bolt, valve seat, barrier film, spring, upper cover, stud bolt is passed through between lower cover, nut, first bolt is fixed, valve body is positioned at the below of lower cover, tapered sleeve is positioned at valve body, fixed by the second bolt between base and valve body, one O type circle is between valve body and tapered sleeve, 2nd O type circle is between base and valve body, plug is arranged on base, valve seat is positioned at the below of tapered sleeve, barrier film is between tapered sleeve and spring.
Preferably, described stud bolt is connected with suspension ring.
Positive progressive effect of the present utility model is: the utility model structure is simple, and maintenance, repair are convenient, reduces cost of production.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model diaphragm type pressure governor.
Embodiment
The utility model preferred embodiment is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model diaphragm type pressure governor comprises the first bolt 1, valve body 2, one O type circle 3, 2nd O type circle 4, plug 5, stud bolt 7, nut 8, upper cover 9, lower cover 10, tapered sleeve 11, base 12, second bolt 13, valve seat 14, barrier film 15, spring 16, upper cover 9, by stud bolt 7 between lower cover 10, nut 8, first bolt 1 is fixed, valve body 2 is positioned at the below of lower cover 10, tapered sleeve 11 is positioned at valve body 2, fixed by the second bolt 13 between base 12 and valve body 2, one O type circle 3 is between valve body 2 and tapered sleeve 11, 2nd O type circle 4 is between base 12 and valve body 2, plug 5 is arranged on base 12, valve seat 14 is positioned at the below of tapered sleeve 11, barrier film 15 is between tapered sleeve 11 and spring 16.Stud bolt 7 is connected with suspension ring 6, diaphragm type pressure governor of so conveniently slinging.
Suction pressure enters valve seat, tapered sleeve, barrier film successively from valve body left end entrance, and now barrier film is subject to the impact of suction pressure.Barrier film has power upwards, and spring is upwards pushed up, and controls the pressure of gas entry outlet. and same, under the action of the spring, barrier film tightness increases.The utility model greatly reduces the quantity of component in valve, and maintenance operation is consuming time shorter.Suction pressure enters the barrier film be in a fixed position by valve body, can provide the pressure reaching upstream pressure value to the epicoele of barrier film; When being in full close position, from from it obtain gaseous-pressure in diaphragm cavity.When downstream pressure increases under the impact that flow declines, reduced by the flow of valve seat, meanwhile, diaphragm cavity internal pressure increases.Pressure increase makes barrier film in the closed position, and the flow passed through reduces, and controlled pressure returns to setting value.The pressure in diaphragm cavity is reduced when instantly having pressure to decline under the impact that traffic demand reduces.Therefore, barrier film only need be closed slightly, and just can ensure that the flow passed through is higher, controlled pressure returns to setting value.
Above-described specific embodiment; the technical problem of solution of the present utility model, technological scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
